In the drawings wherein similar characters of reference indicatecorresponding parts in the several views of the preferred form of theinvention, A designates a-web roll handling and supplying device whichas shown in Figure 1 includes a frame 16, suitably secured to a base orfloor 17. The web roll supporting member or reel 18 as shown in Figure1, has two web rolls supported thereon; i. e., a fresh or replacementweb roll 19 and an exhausting web roll 21, it being understood that ascustomary the web reel support may be swung or rotated to bring the webrolls into desired positions for feeding, transfer, etc., as hereinafterdescribed.

A web end retaining and releasingmember "B forming an important featureof the present invention, a pair of which are employed, one at each endof the fresh roll 19,comprises an arm 22, composed of two pairs ofsections or straps, 23, 24, as shown in Figure 3, slidably an'dadjustably joined in any suitable manner as by the slots 25, formed insections 23, and theT-bolts 26, or other suitable fastening means whichride in the slots 25, and are threadedly engaged in the straps orsections 24, thereby serving to adjustably connect the. sections 23, 24,one of which 24, is slid longitudinally relatively to the other in ordertoaccommodate the member 13 to rolls of various diameters, whennecessary or desired.

The section 23 is formed with or has secured thereto, a collar orannular member 27 which is rotatably mounted either directly on the coreof the web roll which in this instance is the fresh roll 19, or on meanshereinafter described which rotatably support the-web roll. The othersection of the arm 22 is formed with or hassecured thereto a strip ortab holding and cutting instrumentality which comprises a jaw-shapedhead or end 29 having an opening 31, which receives straps or tabs andthe like, hereinafter described, which may have an adhesive on one orboth sides or the top and bottom surface. Two straps 32, 33, preferablyof paper or other suitable strip material, are preferably placed inhelical relation on the roll 19 as shown by way of illustration inFigures 3 and 4 and hereinafter more fully explained. A knife Y orcutting element 34 is hinged or pivoted on a pin 35, secured in the endor head 29 and swings or rocks in a pair of similarly positioned slots36, 37, formed in the upper and lower jaws 38, 39

respectively of the head 29. The knife 34 is main-- tained in normalraised position in the upper jaw 38 by a spring, hereinafter described,thus leaving the opening 31 between the jaws 38, 39 free for receivingthe strap or tab 32, 33 and the other tab hereinafter mentioned; It willbe observed the head of the knife 34 is provided with a widened orflattened portion 41, the: underneath side of which, acts as stop forthe said knife when it abuts against the top of theupper jaw 38 after ithas aoco'mplish'ed'its functions by severing the straps or tabs 32,33,-while the topof the flattened portion acts as anvil or seat whichmay strike against abutments or marginal projections 42, formed orsecured to the brackets or plates hereinafter referred to, forming apart of the webjoining or splicing member hereinafter described morefully.

The webgjoiningg a pair of arms 44, 4 relation to the shaft 46 which isrotatably supr splicing member comprises keyed or fastened in opposedpo'rteddrrbearing hangers 47, suitably secured to slotted plate'48,having bent flanges 49, to which the brush assemblies 51 are fastened,ls adjustably secured by screw bolts 52 which ride in the slots 53formed in the said plate 48.

As best shown in Figures 6. and 7, the head 29 of each of the webretaining and severing members at the opposite ends of the replacementroll 19 is provided with an internal spring 54 mentioned above, which isconnected at one end to an inwardly projecting portion of the knife 34,and at the other end to an internal part of the head 29. The spring 54serves to maintain the knife 34 in normal raised or inoperativeposition, leaving the opening 31 ofthe head 29 free to receive thestraps or tabs 32, 33 preparatory to their severance by the knife'34, asclearly shown in Figure 6.

In Figure 7, the upper or flattened portion 41 of the head of the knife34 is engaged with the abutments or projecting plates 42 and has beenpressed downwardly through the opening 31 to the position shown withinthe slotted lower jaw of the head 29, thus severing the straps 32, 33.

By further inspection of Figures 6 and 7, it will be seen means forsecuring the pair of helically positioned straps or tabs 32, 33,mentioned above, and an additional pair of straps 55, 56,

which are also helically positioned on the body' portion of the roll 19and in crossing or angular relation to the first mentioned pain ofstraps 32, 33,-are provided in the head 29,-the means comprising a pairof small 'rollers 57, having a knurled surface and reduced ends or axles58, which are received in slots 59, formed in a por- ,tion of one of theside walls or surfaces of the head 29 which is formed or provided with apair of shelving recesses or pockets 61 in which the said rollers 57 aresecured by the engagement of the reduced ends 58 of the rollers 57 inthe slots 59, above-mentioned. when the end portions of the tabs orstraps 32, 33, and 55, 56 are passed under the knurled surface of therollers 58, the sliding of the said rollers in the direction of the jaws38, 39 of the head 29 will clampingly confine the straps as the rollersadvance on the inclined or shelving surface 62 of the recesses 61.

The shaft 46 on which the arms 44, 45 of the web-splicing member 43alluded to. above are fastened, has secured thereto, an operating lever63, having a pawl 60 which coacts with a ratchet segment 64 fastened toone of the bearing hangers 47, the lever 63 providing means for manuallyoperating the web-splicing member 43, whenidesired, and for moving itout of the path of the rolls when the roll support is rotated.

In order to bring the web of the deplacement roll'l9 to the same speedas the web of the nearly exhausted roll 21, a feeding belt 65, mountedon a pair of rollers 66, 67, secured on shaft 68, 69 mounted in a framemember 71, is provided. The shaft 69, it will be noted, has a gear 72fastened thereon, the gear 72 being engaged by a gear 73, secured to avertically positioned shaft 74, rotatably mounted in the frame 16andpref'erably having an operative connectionwith the driving system ofthe printing machine, so that the belt 65 travels at substantially thesame speed as the traveling web .W of the exhausting web 21. To

'75 the frame 16. To each of the; arms 44, 45, a dicated om the fore ong details, but it will .end from tearing be more fully understood fromthe following de scription. I

On the free end of the replacement roll 19 which, as viewed in Figures 3and 4, discloses a pair of intersecting or meeting helixes and whichpreferably is torn, notched, cut, or a portion removed therefrom toprovide a more or less 'vshaped edge having the side marginal portionsor tapering fish-tail ends 30, a pair of the binder ribbons or tabs 31,33, referred to above, is pasted, it being observed that the saidribbons or tabs, after pasting, will be positioned in helical relationto the body portion of the replacement roll, and along the edge insubstantial alignment therewith. The notching, tearing, or removing aportion from the free end of the replacement roll is most convenientlyand expeditiously done by first applying or pasting the straps ortabs tothe free end, the straps then serving as guides to tear out the portionof the free end alluded to. The said straps further provide areinforcing means for the end fi. the web to prevent said web en theroll is rotated preliminary to making a web join.

The outer surface of the helically positioned straps 32, 33, is nextsmeared with a suitable adhesive, care being taken to prevent anyadhesive getting on the body portion of the replacement,

'roll, while the ends of the same straps overlapping the opposite endsor sides of the fresh roll 19, are clampingly secured in the upper ofthe pockets 61 of each member B at the opposite ends of the fresh roll19,; by engagingthe said ends under the knurled rollers 5'7 andthrusting the latter towards the jaws 38, 39 until the said overlappingends are gripped between the knurled surface of the rollers and theadjacent shelving surface 62 of each of the pockets or recesses 61.. Theother pair of helically positioned straps or tabs 55, 56, which arearranged in crossing or angular relation to said first-mentioned pair ofstraps 32, 33 are pasted on the body portionof the fresh web roll 19with theirends also secured under the knurled rollers 57 in the lower ofthe pockets 61 of each member B, it being observed that thelast-mentioned pair of straps 55, 56, serve mainly to sustain the webretaining and releasing member B in the operative body portion thereofwhile the latter is rotating in the direction indicated by the arrow,until the moment predetermined for the joining or splicing of the web ofthe replacement roll to the traveling web W of the exhausting roll afterthe peripheral speeds of both webs have been equalized.

Assuming the lower'web roll 21 to have been unwound or used to theamount indicated in Figure 1, the web reel support 18 will be swung orrotated to bring the fresh or replacement roll 19 to the position shownin the last mentioned figure. The feeding belt will now be lowered tooperative engagement with the periphery of the replacement roll 19, andthe latter rotated until the peripheral speed of same is equal to thatof the traveling web W of the now nearly exhausted lower roll 21. J

It will now be seen that as the replacement roll rotates-with its freeend bound to the body portion by the lower pair of .tabs 32, 33, thepair of members B of our invention, at the opposite ends of the freshroll 19, sustained by the upper 'tabs 55, 56, will rotate therewithuntil approximately the moment when the peripheral speeds of the webs ofboth'rolls are approximately equal, whereupon the lever 63 ismanipulated to turn the shaft 46 to swing the brush assemblies 51against the traveling web W of the exhausting roll 21, thereby impingingthe latter against the adhesive-smeared outer surface of the helicallypositioned pair of straps 32, 33 which are pasted on their inner surfaceto the fish-tail edge or end of, the web of the replacement roll 19.Almost simultaneously with the engagement of the brush assemblies 51with the web W for applying same to the sticky outer surface of thestraps or tape 32, the flattened head 41 of each knife or cuttingelement 34, will strike against the abutments 42 of the web splicingmember 43, which may have shock-absorbing material secured thereto,thereby causing the said knife 34 to pass downwardly through theopenings 31 and thus cutting both upper and lower straps or tabs 32, 33,and consequently causing the pair of web-retaining and releasing membersB to completely release the end of the web of the replacement roll 19,now pasted to the web W of the exhausting roll, so that the web of thereplacement roll may serve without the slightest impedance as acontinuation of the web of the exhausted roll without delaying theoperation Iofthe press in the slightest degree. Both of,the'web-retaining and releasing members B, which are freely rotatable0n the core engaging means of the fresh roll or the means supportingsame alluded to above, will now. drop to inoperative or dependingposition, the web of theexhausting roll meanwhile having been severed byany convenient means. This completes the cycle of a change from one rollto another without' stopping or retardation, which may be repeated asmany times as desired, or until the run has been completed. Theinvention is particularly designed and adapted to be operatively appliedto practically all types of machines employing web roll-handlingmechanism, since the application of the tabs and adhesive and theSecuring of the tabs to the permanently mounted pair of members Brequire only a few moments. While the extremities of the fish-tail ends30 on either side of the marginal sides of the free end of thereplacement web roll 19 are shown as arranged in substantially the samerelative position at each end of the web roll 19 and in helical relationto the body portion thereof. It is to be noted that one of the saidfishtail ends 30 may be much shorter than the other or leading fish-tailend, and it will be apparent that if desired, the end of the web may becut on along diagonal in which case, only one of the members B will berequired, since one fork or portion of the fish-tail end alluded toabove would be eliminated.

The helical arrangement of the tab or tabs and the like on the free endof the roll and on the sides or margins of the body portion thereofin'the forms shown, and the tearing or cutting 6 or otherwise removing aportion of the said free end of the replacement roll 19 to form thefishtail or helically positioned ends 30, in themanner indicated above,are also features of the present invention since they achieve by theutmost simplicity of means a highly efiicient way of confining the freeend of the roll to the body portion while the said roll is rotating, itbeing observed that the said fish-tail? ends which are forwardlydirected or leading on the replacement roll 19 while rotating in thecounter-clockwise direction indicated by the arrows in Figures 1, 3,etc., when secured by the above-mentioned tabs or straps, will directlytend to exert a forward pull or drag and thus bind or confine the freeend of the roll, while rotating, to the body portion. As pointed outabove, the tearing of the free end of the replacement roll isaccomplished with certainty and dispatch by preferably first pasting thestrip material or tabs in helical fashion on the free end, and thensimply tearing out the portion of material from the V-shaped spacebetween the said helically positioned straps, using the tabs or strapsas guides for this purpose.

It is to be noted that by pasting the strip ma,- terial or tabs inhelical fashion to the body portion of the roll, instead of parallel'tothe axis or longitudinally of the roll, distinctly serves to prevent airfrom getting under the free end portion of the web, while the roll isrotating, and likewise the tearing or otherwise removing material fromthe free end of the web which is conveniently done by using the tabs asguides for the tearing to provide the fish-tail or equivalent portionsis particularly adapted to prevent air from getting under the free endof the web of the replacement roll during rotation.

In Figure 8, we have illustrated suitable roll chuck mechanism forrotatably supporting web rolls in a web roll or reel support, to whichmechanism the invention can be quickly attached. The chuck mechanismhere illustrated provides means for quick and fine axial adjustments ofthe members which engage the web roll cores so that the rolls may beloaded into the support expeditiously.

By inspection of Figure 8, it will be noted the section 23 of the strapor arm 22 of the web retaining and releasing member B of the inventionis bolted or otherwise suitably fastened to the rotatably mountedannular member or collar 27, forming a part of the chuck mechanismherein mentioned. The supporting arm 78 of the present chuck mechanismis provided with a sliding sleeve 79, having a hand wheel 80, providingfor a quick axial or lateral adjustment of the sleeve '79 and the partsconnected thereto. A block 81, slidably keyed to andconcentricallypositioned within the sleeve has a cone-shaped head 82, which enters-thecore 88 of the web roll 19. The comparatively quick axial or lateraladjustment of the sleeve 79 and the block is effected by an arcuategroove85 in the sleeve '79 and a pin 86 in a hub 8'7, forming a part ofthe supporting arm 78, it being understood that the rotation of the handwheel 80 will move the sleeve when turning,

' in an axial direction by the coaction of the fixed which is fastenedto the block 81. The outer.

portion of the screw 89 is threadedly engaged in the hub 93 of a handwheel 94, employed for making fine adjustments, the hub 93, having anannular recess or groove 95 in which a second thrust collar 96, securedby screw 97 to the handwheel 80,-is engaged.

In operation, it will be observed that when the smaller hand wheel 94 isrotated for fine admeans of supporting web rolls in web reel supports ofthe general character herein indicated.

The parts of the chuck mechanism illustrated in fragmentary section atthe right hand side of the web core 83 shown in Figure 8, are assumed tobe non-adjustable or in fixed position with the exception of therotatable cone-shaped head 82, while nearly all of the parts of thechuck mechanism at the left hand side of the same core 83 are movable oradjustable as indicated, so that the fresh and exhausted web roll can bemoved into and out of position as required, from one side alone of theweb reel support.

In Figures 10 and 11, we have shown a modified form of the inventionwhich requires the use of only one comparatively short strap or tab ateach end of the fresh web roll 19 instead of two as in the form shown inFigures 1 to 9 inclusive. In the present instance, the web releasing andretaining member C 'of the form shown which also serves as an anchoragefor the strip material or tabs differs from the member B in that thejaw-shaped head 98 of the instant form has an offset or laterallyprojecting portion or ledge 99, the top surface of which, as at 101 issubstantially flush with the lower jaw 102 of the head 98. A- portion ofthe single binder ribbon or tab 103 here employed, after one end thereofhas been pasted on its under surface to the body portion of the roll 19,preferably in helical relation thereto, as shown in Figure 11, is passedover the said top surface 101, thence downwardly and around the lowerprojecting portion 104 of the said ledge 99 and thence obliquely orangularly upward as at 105 over the top. of that portion of itself whichrests on the top of the ledge 99, continuing in a diagonally crossingdirection over an adjacent edge of the free end of the fresh web roll 19to which it is pasted on its inner surface. While the sequence justdescribed is preferable, since the portion of the binder strip 103adhering to the free endis uppermost and consequently free afterseverance by the knife 106 to be carried away with the traveling web ofthe replacement roll after being glued thereto, it will be understoodthat, if desired, the said strip 103 may first be pasted to the free endof the replacement roll, then passed over those portions of thejaw-shaped head 98 enumerated above, then passed over the portion of thestrip sticking to the free end, and finally pasted to the body portionof the replacement web roll. In the last recited sequence, the placingof that portion of the strip material immediately adhering to the freeend of the web underneath the portion of the strip glued to the bodyportion would not be as advantageous as the preferable arrangement sincethere would-be a temporary overhanging or superincumbent por-.

tion of strip material that would be thrust aside as the free end of thereplacement web became 5 inclusive, wherein the free end of thereplacement roll is notched by first pasting the straps 32, 33

thereon and then a portion of the free web end torn out while using thesaid straps as guides. The second pair of straps 55, 56 are subsequentlypasted. on to the body portion of thereplacement roll and may be usedatonce to support the member 13 either before or after the smearing ofthe outer surface of the first-mentioned pair of straps 32, 33 withadhesive. The knife 1060f the member C performs practically the samefunctions as inthe form shown in Figures 1 to 9 inclusive.- In thisform, however, the folded over or crossing portions of the single strapor tape 103 at each end of the web roll 19, are simultaneously cut asthe knife 106 of each of the pair of members C employed, one at each endof the roll 19, engages the abutment or trigger projections mentionedabove. 1 a

In Figures 12, 13 and 14, a modified form of the invention is shownwhich employs one strip of .adhesive tape or strap, and-eta, 106, whichmay be perforated or creased as at 107 to facilitate tearing orseverance thereof, is pasted to the free end of the web roll 19, inhelical relation to the body portion thereof, one end or portion of thetape 106 being in a strap or tape and the like securingmember 108 whichis similar in some respects to the strap or tab securing member, bestshown in Figures 6, 7 and 9. The member 108 includes a frame or shell109, having a shelving pocket or recess 111, in which a tape or ribbon,engaging roller 112, having a knurled surface is arranged. The-knurledroller 112 has reduced ends 113, which are slidably received inelongated slots 114, formed in the shell 109, thus permitting the rollerto be slid in the pocket 111 for the purpose of clampingly engaging thetape 106 confined against the shelving surface the said pocket 111 andthe adjacent knurl surface of cal the roller 112 in the manner describedabove in connection with the details shown in Figures. 6, 7 and 9. Aportion of the shell or frame 109 has flanges asat'l15 which arereceived in grooves 116, formed in an annular member 117 for a purposewhich willappear hereinafter, while a rack 118 is provided on one end oredge of the shell 109. The rack 118 is engaged by a pinion 119 rotatablymounted on a stud or pin 121, the'pin 121 being secured to the annularmember'117, the

pinion 119 meshing with a rack segment 122,

formed on an arcuate strap 123, which is fastened to an annular portion124 formed with or secured to an arm or trigger member 125, which coactswith a pin or'stop 126, secured to an arm 127, or a part of the adjacentweb splicing member or frame. The arm 125 is held in the normal positionshown against a stop pin 128, and is secured to the annular member 117by-a spring 129, fastened at one end thereto, the other end of thespring being attached to a cam-shaped member or latch 131, having a slot132, in which rides a pm 133, secured to a forked extension or proj'ec-,tion 134, of the shell 109.. The annular member 117, as indicated inFigure 12 by the dotted line at the lower portion thereof, may have acounterbalaneing weight 130, if desired. The camshaped member or latch131 is provided with a pin 135, fastened thereto, to which is securedone of the looped ends 136, respectively of a clutch member or band 137,frictionally engaged with the hub 138 of the cone-shaped head 139 of theweb core engaging memberl141, shown in fragmentary section in Figure13.- The other looped end 142 of the clutch member or band 137 isfastened on a pin 143 on the annular member 117, serving as a pin orfulcrum for the camshaped member or latch 131', the pin 143 traveling.in an arcuate slot 144, formed in the annular portion 124 of the arm125, for a purpose hereinafter described. The functions and manner ofoperation of the modified form of the invention shown in Figures 12, 13and 14 has been in part indicated by the foregoing details, but willbemore fully understood from the following description:

Assuming as best shown' in Figure 12, the fresh" or replacement web roll19 has been operatively mounted on the member 141 with its free endnotched or torn to provide the helically positioned portions engaged bythe adhesive tape 106, a portion of which latter is clampingly held inthe tape securing member 108; and that the said fresh roll and thecore-engaging member are revolving at normal press operating speed, andalso assuming the clutch 137 to be as illustrated, in frictionalengagement with the hub 138, and the trigger arm 125 to have struckagainst the stop 126, it will be noted that further rotation in acounter-clockwise direction of the assembly shown in Figure 12 willfirst cause the immediate severance or breaking of the helicallyarranged adhesive paper tape 106 at the point of the perforations 107,thus completely liberating the free end of the fresh roll 19 at the timewhen the traveling web of the exhausted roll is being or has beenapplied to the sticky upper surface of the said tape in order to bind orsplice same, and consequently the web of the fresh roll, to the web ofthe-exhausted roll, in the manner described above in connection withFigures 1 to 9 inclusive.

It is to be noted that the momentum of the annular member 117 will carryit ahead after 4 rack 118 and rack segment 122, and consequently causingthe shell 109 and its attached rack 118. to move in the groove or slides116.- The movement of the tape securing member 108 along the grooves 116will, as mentioned above, first cause the immediate severance orbreakage of the adhesive paper tape 106 at the point of the perfora-'tions 107 thus completely liberating the free end of the roll 19 fromthe body portion of the roll in order to permit the unimpeded attachmentof the free end of the roll to the traveling web.

The separation of the looped ends 136 and 142 will free the clutch band137 from frictional engagement with the hub 138 of the web-core engagingmember 141, and as a consequence" will permit the hub 138 to turnfreely relatively to the clutch assembly and the parts connectedthereto. It willbe noted that when the clutch band 137 is released afterthe pin 133 on the moving tapeengaging member 108 has travelled in theslot 132 sufiiciently to engage the end of same and move the latch 131'about as pivot pin 143 enough to latch 131 to the position shown inFigure 12 will be counter-balanced by the available torque of .,therevolving hub communicated through the now slipping clutch band 137 onthe said hub. This will produce at the time now indicated, a conditionof equilibrium between the clutch and the tension spring 129 resultingin an idling of the 'which comprises strip material pasted adjacent anedge of said free end so as to overlap an end of the body portion andanchored at said end to a member rotated with said web roll.

2.
